A WARNING
--Always pay attent ion to traffic even when
the cruise co ntrol is switched on . You are
always responsib le for your speed and
the distance between your veh icle and
other veh icles .
- For safety reasons, the cruise cont ro l
should not be used in t he city, in stop­
a nd -go traffi c, on twisting roads and
when road con ditions are poor (such as
ice, fog, gravel, heavy rain and hydro ­
p la ni ng) -risk of accident .
- Tu rn off the cruise co ntro l temporarily
when entering turn la nes , highway exit
lanes or in constr uction zones .
- Please note that inadve rtently "res ting"
your foot on the accelerator pedal causes the cruise control not to brake . This is
because the cruise control is overridden by the driver's acceleration.
- If a brake system malfunction s uch as
overheating occurs when the cruise con­
trol system is switched on, the braking
function in the system may be sw itched
off . The other c ruise control functions re­
main act ive as long as the indicato r light

is o n.
(D Tips
The brake lights illum inate as soon as the
brakes decele rate automatically .
Changing speed
Applies to vehicles: with cruise control
• To increase/de crease the s peed in inc re­
ments, tap the lever in the
0 10 direc tion
c::> page 82 , fig . 83
• To increase/decrease the s peed quick ly, hold
the lev er in the
0 10 d irect ion until the de­
sired speed is displayed .
You can also press the accelerator pedal down
to increase your speed, e .g . if you want to
pass someone. The speed you saved earlie r
will res ume as soon as you release the acceler-
ator pedal. ..,.

194 Intelligent technology
vehicles with adaptive cruise control*, the
brake assist system is more sensitive if the
d istance detected to the vehicle ahead is too
smal l.
Anti -slip regulati on (ASR )
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to
the road conditions. This makes it easier to
start, accelerate and drive up hills.
Electronic diffe rential lock (EDL )
The EDL brakes wheels that are spinn ing and
transfers the drive power to the other wheels .
This function is available up to abo ut 75 mph
(120 km/h) .
I n extreme cases , ED L automat ic all y switches
off to help keep the brake on the braked whee l
from overheating . EDL will switch on again au­
tomatically when conditions have returned to normal.
Dynamic st eering*
On vehicles with dynamic steering* , ESC helps
stabilize the steering in critical situations .
Electronic interaxle differential lock */
s elective whe el torque control *
The electronic in teraxle d iffe ren tial lock (fro nt
wheel drive) or the select ive whee l torq ue
control (a ll-wheel drive) operates when driv­
ing throug h curves . The front whee l on the in­
side of the curve or both wheels on the inside
of the curve are braked selectively as needed.
T his minimizes sliding in the front wheels and
allows for more precise driving through
curves . The applicable system may not acti­
vate when d rivi ng in wet or snowy conditions.
_& WARNING
- E SC, ABS, ASR, EDL, dynamic steering*
and the E lec tronic interaxle differentia l lock
*/se lective whee l torque control*
cannot overcome the laws of physics.
This is especially important on slippery
or wet roads .
If the systems beg in acting
to stabilize your veh icle, you should im­
mediately chang e you r speed to match
the road and t raffi c conditions. Do not
let the increased safety provided by
these systems temp t you to take risks.
Doing so will increase the risk of a loss of
veh icle cont ro l, collision and serio us per­
sonal injur ies.
- Always adapt your speed to road, traffic
and weather conditions . The risk of los­
ing control of the vehicle increases when
driving too fast, espec ially through
curves and o n slippery or wet roads, and
when dr iv ing too close to vehicles up
a head . ESC, ABS, the brake ass ist sys­
tem, ED L, ASR, dynam ic steeri ng* and
the Electronic in terax le different ial
loc k*/se lective whee l torque control*
cannot prevent collisions .
- Always accelerate wi th spe cial care on
even, smooth s urfaces such as those that
are wet or covered with ice and snow.
The drive wheels can spin even with
these assistance systems that cannot al ­
ways he lp to reduce the risk of loss of ve­
hicle control.
(D Tips
- ABS and ASR only wo rk correctly when
all four wheels are equipped with identi­
cal tires . D ifferent tire si zes can lead to a
reduction in engine powe r.
- You may hear noises when the systems descr ibed are working.
- If the ind icator light
Bl or fJl1 (USA

than is being generated and ensures an opti­mal state of charge for the battery.
@ Tips
- But even energy management cannot
negate the limits o f physics. Consider
that the power and life of a battery are
limited.
- If starting ab ility is threatened, the indi­
cator light (•) appears
¢ page 17.
What you should know
The highest priority is given to maintaining
starting capability.
The battery is severely taxed in short-dis tance
driving, in city traffic and d uring the co ld time
of year . Abu ndant e lectrica l energy is re­
q uired, but only a litt le is generated . It is also
cr itical if the engine is not runn ing and electri­
cal components are turned on. In th is in­
stance energy is being consumed but none is
be ing generated.
It is in precisely these situations that you w ill
notice energy management actively regulat­
i n g the distribution of energy.
Vehicle stand s for an e xte nded period
If yo u do not drive you r vehicle over a period
of severa l days or weeks, electrical compo­
nents are grad ually cut back or switched off.
This reduces energy consumption and main­ tains starting capab ility over a longer per iod.
Some of the conven ience functions may not
operate, such as the inter ior lights o r the
power seat adjustment. The conven ience
f u nctions will be ava ilable again whe n you
switch on the igni tion and start the engine.
With the engine turned off
If you lis ten to t he radio, for example, with
the eng ine turned off or use othe r MM I fu nc­
tions, the bat te ry is being discha rged .
If starting capability is jeopardized due to en ­
e rgy consumpt ion, the follow ing warning ap­
pears in the MMI disp lay :
Int ellig ent technolog y 199
Plea se start the engine soon or the sy stem
will be turned off .
The wa rni ng ind ic ates th at the sys tem w ill be
t u rned o ff autom atically a fter 3 minu tes. If
you w ish to continue using the funct ions, yo u
have to start the engine.
With the engine running
Althoug h elec trical energy is generated when
t h e ve hicl e is being driven, t he battery can be­
come d isc harged. This happe ns mostly when
little energy is being generated and a g reat
deal consumed and the battery's state of
charge is not opt imal.
T o b ring the energy ba lance back in to equili ­
brium, consumers which req uir e especially
l a rge amounts of energy a re temporari ly cut
back or sw itched off. Heat ing systems in par­
ticular require a great deal of energy. If you notice, for example, that the heated seats* or
the heated rear window are not heating, they
have been temporarily cut back or switched
off . These systems w ill be availabl e again as
soon as the ene rgy balance has been restored.
You w ill also notice that engine id le speed has
been increased slightly . Thi s is no rmal and not
a cause for concern. By inc reas ing engi ne id le
speed the additional e nergy requi red is gene r­
ated and the b attery is charged.

@ Tips
The consumption estimates as published by ENVIRONMENTAL PROTECTION AGENCY (EPA) and Transport Canada may not corre­
spond to your actual consumption on the
road, wh ich will vary depend ing upon vehi­
cle load and speed, road and weather con­
ditions, tr ip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating.
~ Avoid unnecessary accelerating and braking.
Vehicles use the most fuel when they are ac­
celerating . If you anticipate what is go ing to
h appen next, you will need to brake less and,
thus , accelerate less . Let the vehicle coast
wheneve r poss ible -fo r example when you see
that the nex t traffic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
~ T ry and keep well below your car's max imum
speed.
Accelerating gent ly reduces fuel consump­
tion, engine wear, and does not disturb the
environment .
Fuel consumption, exhaust emissions and en­
g ine no ise increase d ispropo rtionately at high
speeds . If you dr ive at approximately three
quarters of top speed, fue l consumption will
be red uced by one ha lf. Never dr ive faste r
than the posted speed limit and wea ther con­
d itions permit.
Reducing unnecessary idling
E ven when your car is just idling it burns up
fuel .
~ Shut the engine off when you are not dr iv ing
the vehi cle.
Dri vin g and en vironm ent 203
~ Do not warm up the vehicle by lett ing the
engine run at id le .
T he id ling phase is au toma tic ally red uced for
vehicles with the Start -Stop -System . It is eff i­
cient to switch off the engine in vehicles with­
out the Start-Stop-System when stopp ed at
railroad crossings and long red lights. Turning
the engine off for jus t 30-40 seconds saves
more fuel than is burned by start ing the en-
. . gme again .
It takes a long t ime for the engine to warm up
fully when it is run ning at id le. However, wear
and noxious emissions are especia lly high
when the engine is warm ing up . So you should
dr ive away as soon as you start the engine and
avo id running at high rpms whi le the engine is
sti ll warming up.
(L} Note
Do not leave eng ine idling unattended af­
ter start ing .
If wa rni ng lights sho uld come
on to indicate improper ope ration, t hey
wo uld go unheeded . Extended idlin g also
produces heat, wh ich could res ult in ove r­
heating or other damage to the veh icle or
other p roperty .
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel.
~ Have your ve hicle servi ced at reg ular i nter-
vals .
By havi ng your ve hicle regu la rly se rviced by an
Audi dealer he lps to ensu re tha t it ru ns prop­
erly and economically . The condition of your
vehicle not on ly affects its safety and ability to
ho ld its va lue, it a lso affects
fuel consump­
tion .
Check your oil e ach time you fill your tank.
T he amou nt of oi l used is re lated to engine
load and speed.
It is normal for the oil consumption of a new
engine to reac h its lowest value after a certa in
mileage has been d riven . .,..

-Blend must contain not more than 15%
MTBE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perform
espec ially we ll for winter or summer driving.
During seasonal change-over, we suggest that
you fill up at busy gas stat ions where the sea­
sonal adjustment is more likely to be made in
time .
(D Note
-Methanol fuels which do not meet these
requirements may cause corrosion and
damage to plastic and rubber compo­
nents in the fuel system .
- Do not use fue ls that fail to meet the
specified criter ia in this chapter.
- If you are unable to determine whether
or not a particular fue l blend meets the
specifications, ask your service station or
its fuel supp lier.
- Do not use fuel for which the contents
cannot be identified.
- Fuel system damage and performance
problems resulting from the use of fuels
different from those specified are not
the responsibility of Audi and are not
covered under the New Vehicle or the Emission Control System Warranties.
- If you experience a loss of fuel economy
or driveability and performance prob­ l ems due to the use of one of these fuel
blends, we recommend that you switch
to unblended fuel.
Gasoline additives
A major concern among many auto manufac­
turers is carbon deposit build- up caused by
the type of gasoline you use.
Although gasoline grades differ from one manufacturer to another , they have certain
things in common. All gasoline grades contain
substances that can cause deposits to collect
on vital engine parts, such as fuel injectors
and intake valves. Although most gasoline brands include additives to keep engine and
Fuel supply and filling your fuel tank 215
fuel systems clean, they are not equally effec ­
tive .
A udi recommends using TOP TIER Detergent
Gasoline. For more info rmation on TOP TIER
Detergent Gasoline, please go to the official
website (www.toptiergas.com).
After an extended period of using inadeq uate
fuels, carbon deposit build-ups can rob your
engine of peak performance.
Q) Note
Damage or malfunction due to poor fue l
quality is not covered by the Aud i New Ve­
hicle Limited Warranty.
Diesel fuel
Applies to veh icles: w ith diese l eng ine
Always use ULSD (Ultra Low Sulfur Diesel)
No. 2. The ULS D No. 2 meets the ASTM D975.
D iesel fuel w ith concentrations of biodiese l
highe r than 5 % such as Bll, B2O or BlOO are
strictly prohib ited.
Serv ice stat ion fuel pumps are labeled with
the correct fuel informat ion for easy recogn i­
t ion by the user. If the diesel fuel pump is not
labeled ask the station operator what fuel is
being dispensed before filling up your vehicle.
ULSD No. 2 may not be available outside the
USA and Canada. Be sure to check before trav­
eling to other countries.
ULSD No. 2 can become thicker in very cold
temperatures, and this can impair the en­ gine's start ing and running. Depending on the
season, gas stat ions provide ULSD No. 2 that
flows better in cold temperatures so that you
can continue operating your vehicle as usua l.
(D Note
-Your vehicle's diesel engine was de­
signed soley for use with ULSD No. 2.
Th erefore, never use gasoline, heating
oil, other f uels or flow improvers . These
contain substances that wi ll severely
damage the fuel system and the engine. .,.

228 Check ing and filling
- Always dispose of used engine oil proper ­
l y . Do not dump it on garden soi l, wood­
ed areas, into open streams or down
sewage dra ins.
- Recycle used engine oil by taking it to a
used engine oil collection facility in your
area, or contact a service station.
Engine cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro­ tects the engine from freezing in the winter.
The cooling system is sealed and generally re­
qu ires little attention.
The cooling system has been filled at the fac­
tory with a permanent coolant which does not need to be changed. The coolant consists of a
mixture of spec ially conditioned water and the
manufacturer's glycol-based coolant addi-
tive G13 antifreeze with ant icorros ion addi­
tives (50% for USA models; 60% for Canadian
models). This mixture both assures the neces­
sary frost protection and protects metal com­
ponents in the engine's coo ling system from
corrosion and scaling . It also raises the boil­
ing point of the coolant.
Do not reduce the concentration of the coo l­
ant in the summer by adding plain water.
The
p ropo rtion of coolant add itive must be at
l e a st 50 % but not mo re th an 60 %
to ma in­
tain antifreeze protection and cooling efficien­
cy . If the coolant frost protect ion is too low,
the coo lant cou ld freeze and damage the veh i­
cle heating and eng ine cool ing system.
For year-round driving, antifreeze is added at
the facto ry for temperatures down to:
- -31°F(-35°C)USA
- -40 °F ( -40 °C) Canada.
If you m ust add coo lant, use a m ix tu re of wa ­
ter and coo lant addit ive . M ixing the coolant
additive with disti lled water is recommended .
A WARNING
Before you check anything in the engine
compartment, always read and heed all
WARNINGS~ &.
in Working in the engine
compartment on page
222 .
(D Note
-Before winter sets in, have the coolant
checked to see if the coolant additive in
your vehicle is sufficient to meet the cli­ mate conditions. This is especia lly impor­
tant if you live in a reg ion where t he win ­
t er is ex treme ly cold. If necessary, in­
crease the p roportion of coo lant add it ive
to 60% .
- When adding coolant addi tive to yo ur
c ooling sys tem, remembe r:
- We recommend us ing on ly coolant ad­
d itive G12++ or G13 (check the label)
for your vehicle . This coolant additive is
ava ilable at autho rized Aud i dea le rs.
Other types of antifree ze ca n sign ifi­
ca ntly reduce co rros io n protec tion. The
res ulting corrosion c an cause a loss of
coolant and serious engine damage.
- Do not add any type of r ad iator le ak seal­
ant to yo ur vehicle 's engine coolant .
Adding radiator repair flu id may adverse­
ly affect the function and performance of
your cooling system and cou ld resu lt in
damage not covered by your New Vehicle Limited Warranty.
Checking the engine coolant level
-
The engine coolant level can be checked with
a quick glance.
